26: # I am using a multiple pass-through approach to parsing
27: # the lpml file. This saves memory and makes sure the server
28: # will never be overloaded.
29: #
30: # This is meant to parse files meeting the lpml document type.
31: # See lpml.dtd. LPML=Linux Packaging Markup Language.

36: **** ERROR ERROR ERROR ERROR ****
37: Usage is for lpml file to come in through standard input.
38: 1st argument is the mode of parsing.
39: 2nd argument is the category permissions to use (runtime or development)
40: 3rd argument is the distribution (default,redhat6.2,debian2.2,redhat7.1,etc).
41: 4th argument is to manually specify a sourceroot.
42: 5th argument is to manually specify a targetroot.
43:
44: Only the 1st argument is mandatory for the program to run.
45:
46: Example:
47:
48: cat ../../doc/loncapafiles.lpml |\\
49: perl lpml_parse.pl html default /home/sherbert/loncapa /tmp/install
